Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to important documents such as banknotes, stock certificates, bonds, passports, and various certificates (hereinafter referred to as "security printed matter"), and is particularly difficult to forge or falsify. The present invention relates to a security printed matter that uses small characters for printing.

[0002]

2. Description of the Related Art In recent years, with the rapid progress and spread of computer image processing technology due to the rapid progress of computer hardware and the progress of image processing programs operating on the computer, even in the field of securities printed matter, Forgery and falsification using these computer image processing techniques are implemented, and the forgery and falsification methods are becoming more sophisticated and diversified.

[0003]

Conventionally, as a method of forgery or falsification using these computer image processing techniques, imitation or duplication by a copying machine or the like has been mainly performed in the past. Techniques for preventing imitation and duplication by copy machines and the like have become widespread, and imitation and duplication by these copy machines and the like are becoming difficult to carry out, and since computer image processing technology has improved as described above, In recent years, since the plates themselves have been created and imitated by visual inspection, etc., there is a strong demand for a security printed matter that is excellent in copy protection or counterfeiting prevention for creating and imitating these plates themselves. It had been.

Therefore, the present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a security printed matter excellent in copy prevention or forgery prevention against making and imitating the plate itself.

[0005]

In order to solve the above-mentioned problems, a security printed matter on which a small symbol character group consisting of a large number of minute symbol characters of the present invention is printed, together with necessary information about the security, a large number of minute symbols. And / or a microprint character group consisting of microcode characters composed of microcharacters, which is at least 2 as the same microsymbol or typeface of the micro character that constitutes the above micro code character group. It is characterized by including the different types of fonts mentioned above. According to this feature, at least two or more different types of typefaces are used as the same type of minute symbols or typefaces of minute characters that constitute the minute symbol character group, and these typefaces are matched for each minute symbol character. Since it is necessary to produce the plates by making them, it is possible to make the production of these plates extremely difficult, and thus it is possible to obtain a security printed matter that is excellent in copy protection or forgery prevention against making and imitating the plates themselves. .

[0006] The security printed matter on which the micro symbol characters group consisting of a large number of micro symbol characters of the present invention is printed, the two or more different types of typefaces are generally known typefaces and generally used typefaces. It is preferable to include a unique typeface that is not used. In this way, using the original typeface makes it even more difficult to create the plate itself.

[0007] It is preferable that the securities printed matter on which the minute symbol character group consisting of a large number of minute symbol characters of the present invention is printed has only one typeface. If you do this,
By not using a large number of original typefaces and only one typeface in the known typeface, it becomes difficult to notice that the original typeface is used, and by checking these original typefaces, it is possible to reproduce or Forgery can be easily identified.

In the security printed matter on which the minute symbol character group consisting of a large number of minute symbol characters of the present invention is printed, the minute symbol character group has a prescribed number of minute symbols and / or a prescribed length. It is preferably composed of repeating units. In this way, symbols and characters with similar but different typefaces in the repeating unit will be adjacent,
It is possible to make the specification of these typefaces complicated, and to make the edition itself even more difficult.

In the securities printed matter on which the minute symbol character group consisting of a large number of minute symbol characters of the present invention is printed, the fonts of the many minute symbol characters forming the minute symbol sentence group are randomly selected. Is preferred. By doing so, the arrangement of the typefaces becomes random, and the work of specifying the typefaces can be made more difficult, so that the plate itself can be made even more difficult.

In the security printed matter on which the minute symbol character group consisting of a large number of minute symbol characters of the present invention is printed, specific information can be defined by selecting the same typeface in the minute symbol character group. In addition, it is preferable to arrange a typeface. By doing so, it becomes possible to conceal specific information in the minute symbol character group.

In the securities printed matter on which a group of minute symbol characters composed of a large number of minute symbol characters of the present invention is printed, it is preferable that the typeface defining the specific information is the original typeface. With this configuration, by defining the specific information by the unidentified unique typeface, the selection probability of these unidentified unique typefaces can be lowered, and the confidentiality of the specific information can be improved.

In the security printed matter on which a group of minute symbol characters composed of a large number of minute symbol characters of the present invention is printed, the specific information is information that matches necessary information about the certificate printed on the certificate. Is preferred. By doing so, it is possible to easily confirm the authenticity of the security by comparing the specific information with the necessary information regarding the security.

In a security printed matter on which a group of minute symbol characters composed of a large number of minute symbol characters of the present invention is printed, the typeface defining the specific information is a functional ink different from the printing ink of other typefaces. It is preferable that it is printed. With this configuration, specific information can be recognized quickly and accurately by using the function of the functional ink.

It is preferable that the functional ink of the security printed matter on which a group of minute symbol characters composed of a large number of minute symbol characters of the present invention is emitted when irradiated with light in a specific wavelength region. With this configuration, specific information can be recognized only by irradiating light in a specific wavelength range.

In the security printed matter on which a group of minute symbol characters composed of a large number of minute symbol characters of the present invention is printed, it is preferable that the light in the specific wavelength region is ultraviolet light. By doing so, since the chance of being irradiated with ultraviolet rays is extremely rare in normal use, it is possible to prevent the counterfeiters from perceiving that the specific information is hidden in normal use. can do.

[0016] In the security printed matter on which a group of minute symbol characters composed of a large number of minute symbol characters of the present invention is printed, it is preferable that the minute symbol characters have a size that is difficult or impossible to visually read. By doing so, it is possible to prevent the forgery or the like from recognizing that the minute symbol characters are printed, and it is possible to improve the forgery prevention effect.

In the security printed matter on which the minute symbol character group consisting of a large number of minute symbol characters of the present invention is printed, a large number of minute symbol characters constituting the minute symbol character group are arranged continuously and curvedly. It is preferably printed so as to form a color pattern.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the security printed matter according to the present invention will be described below based on examples with reference to the drawings. In the following embodiments, a gift certificate is shown as an example of a security print, but it goes without saying that the present invention can be applied to other security prints.

(Embodiment 1) FIG. 1 is a view showing a gift certificate which is Embodiment 1 of a security printed matter of the present invention. As shown in FIG. 1, the gift certificate A1 of the first embodiment has basic characters 1 and 5 on the surface of which the necessary information regarding the security is visually displayed, and
Design character 2, minute character 3, OCR character 4, MICR
Characters such as character 6 and colorless fluorescent character 7 are printed.
Further, the design character 2, the minute character 3, and the basic character 5 are composed of a character group formed by collecting a large number of characters. The character group 3'consisting of the minute characters 3 is formed by regularly arranging a character string of a repeating unit "Japan", which is a predetermined number of character strings, and includes 520 minute characters 3 in total of 65 columns x 8 rows. I'm out. Thus, by regularly arranging the character string of the repeating unit "Japan" which is a predetermined number of character strings to form the character group 3 ', "day" which constitutes these repeating units,
Since the letters "book" are arranged adjacent to each other in different typefaces, as will be described later, it is possible to make the identification of these typefaces complicated, and it is more difficult to make a forgery or reproduction plate. However, the present invention is not limited to this, and the character string of the repeating unit having the predetermined character length as described above may not be used.

The size of the minute characters 3 may be such that the characters are difficult to read with the naked eye, or the size of the characters may be extremely small and unreadable. Specifically, as the unreadable size is 0.4 mm or less, it is almost unreadable, and if it is 1 mm or more, it is readable by almost all people. It can be said that larger characters are hard to read as characters with the naked eye.

As described above, setting the size of the small character to a size that is difficult to read as a character with the naked eye or a size that is not readable is recognized by a forger or the like that a minute symbol character is printed. However, the present invention is not limited to this, and the size of these minute characters may be appropriately selected.

Further, in this embodiment, as shown in FIG. 1, the minute character group 3'has a shape in which the characters of "Japan" are arrayed in the vertical and horizontal directions. The present invention is not limited to this, and by arranging these minute characters in a continuous and curved manner, it may be configured to be recognized as a more complicated color pattern.

When the area 1b of the minute character group 3'is magnified and observed as shown by the arrow, the actual typeface of minute characters,
In the first embodiment, the typefaces of “day” and “book” are the first typeface 3
A, second typeface 3B, third typeface 3C, fourth typeface 3
5 different typefaces of D and the 5th typeface 3E are selected,
It is arranged. Among them, the typefaces 3A to 3D are commonly used known typefaces, specifically, Mincho typeface, Gothic typeface, line typeface, open typeface, etc., while the typeface 3E is not generally used. It is a unique typeface.

As described above, although the present embodiment is described with five types of typefaces, there is no limitation on the number of typefaces, and it is sufficient that at least two different typefaces are included.

Further, in this embodiment, one unique typeface is used as described above. However, using these unique typefaces makes it even more difficult to make a plate in forgery or reproduction by using these unique typefaces. However, the present invention is not limited to this, and as long as it is composed of at least two different typefaces, it is not necessary to use a unique typeface. .

Further, in this embodiment, as shown in FIG.
Of the five types of typefaces, one is a unique typeface, and doing this makes it difficult for counterfeiters to notice that they are using these unique typefaces. However, the present invention is not limited to this, and a plurality of unique typefaces may be used.

Then, the 5 used in these examples.
Regarding the arrangement of the typefaces, these typefaces 3A to 3E are arranged at random, and such a random arrangement of the typefaces can make the specific work of the typefaces more difficult. It is preferable because the plate itself can be made difficult at the time of forgery and a high anti-counterfeiting effect can be obtained, but the present invention is not limited to this, and a certain regularity in arrangement of these typefaces You may have it.

According to the security printed matter of Example 1, the anti-counterfeiting effect that the minute characters have conventionally can be further enhanced. This is because the counterfeiter does not notice the change in the typeface of the character string, even if he or she pays attention to the arrangement of the characters, and when the forgery is made with the same typeface, the characters in the predetermined typeface of the minute character group 3 ', especially the special typeface are confirmed This is because it is possible to easily discriminate the authenticity.

Even if this typeface change is noticed, the minute characters 3 of this embodiment are composed of five types of typefaces, and
Since the arrangement is 65 columns × 8 rows, the number of characters is 520. For this reason, forgers are required to make accurate copies while parsing each character.
Due to the great effort involved in the analysis of these typefaces, their reproduction can be very difficult.

Further, increasing the number of minute characters, reducing the character height of minute characters to 250 μm or less, increasing the number of typefaces that are not generally used, and disposing different typefaces is not regular. Since the counterfeiter must surely confirm the original minute characters one by one by randomly arranging them, forgery resistance (a force that makes it difficult to forge, also called anti-counterfeiting effect). To improve.

(Embodiment 2) FIG. 2 is a view for explaining a gift certificate which is Embodiment 2 of the securities printed matter of the present invention. As shown in FIG. 2, the gift certificate A2 of the second embodiment is almost the same as the gift certificate A1 of the first embodiment. Therefore, the gift certificate A2 of the second embodiment
Regarding the above, the description of the same configuration as that of the gift certificate A1 of the first embodiment will be omitted, and only the configuration of the characteristic minute character group will be described.
The gift certificate A2 includes five types of typefaces as in the first embodiment, but is a unique typeface 3E that is not generally used.
Is the specific information (“1000” in this embodiment) that the gift certificate A2 tries to conceal, as shown in the enlarged view indicated by the arrow.
Are arranged to define the. On the other hand, the generally used typefaces 3A to 3D are randomly arranged at positions other than the position where the typeface 3E is arranged.

As described above, in the second embodiment, the unique typeface is arranged so as to define the specific information "1000", and this is specified by an unidentified unique typeface. By defining such information, it is preferable that the selection probability of these unknown typefaces that are not publicly known can be lowered and the confidentiality of the specific information can be improved, but the present invention is not limited to this. Instead, the typeface defining these specific information may be another typeface known in the art.

Therefore, in the gift certificate A2, the fonts 3A to 3D are used.
If the characters of the typeface are deleted (the deleted state is shown as being filled in black as shown in the enlarged view below),
Hidden information 3 "1000" consisting of typeface 3E
F can be taken out. Specifically, the authenticity determination is performed by visually recognizing only the characters of the typeface 3E and reading and concealing the concealed information 3F, or by mechanically pattern-recognizing only the characters of the typeface 3E and taking out and reading the whole. Secret information 3F
Can be read.

In the present embodiment, this information 3F corresponds to "1000" corresponding to the face value printed with the basic character 1 of the gift certificate A2, which is the necessary information about the security, in this embodiment.
It is preferable because it can be an effective means of authenticity discrimination,
The present invention is not limited to this, and these hidden information 3F may be information other than necessary information regarding securities, for example, a symbol such as the logo of the issuing company, and these hidden information 3F are appropriately selected. Just do it. The hidden information 3F is not limited to letters and numbers, but may be figures or pictures.

(Embodiment 3) FIG. 3 is a view for explaining a gift certificate which is Embodiment 3 of the printed matter of the present invention. As shown in FIG. 3, the gift certificate A3 of the third embodiment is almost the same as the gift certificate A2 of the second embodiment. Therefore, the gift certificate A3 of the third embodiment
Regarding the above, the description of the same configuration as that of the gift certificate A2 of the second embodiment will be omitted, and only the configuration of the characteristic minute character group will be described.
The gift certificate A3 includes five types of fonts as in the first and second embodiments, but the unique font 3E that is not generally used is a gift certificate A3 as shown in an enlarged view indicated by an arrow. Is arranged so as to define specific information to be concealed (“1000” in the third embodiment as in the second embodiment), and the unique typeface 3E is irradiated with ultraviolet rays which is a functional ink. It is printed with ultraviolet light emitting ink (fluorescent ink) that emits light (fluorescent light).

On the other hand, the other commonly used typefaces 3A to 3D are randomly arranged at positions other than the position where the typeface 3E is arranged, and are printed with normal ink. By irradiating the securities with ultraviolet rays, the portion of the original typeface 3E printed with the ultraviolet light emitting ink emits light, and "1000" composed of the typeface 3E.
The hidden information 3G will be visible.

Printing the typeface 3E arranged so as to correspond to the secret information 3G as described above with the ultraviolet light-emitting ink (fluorescent ink) that emits light (fluorescent) by irradiation of ultraviolet rays, which is a functional ink, It is preferable because it can quickly and accurately recognize concealed specific information by light emission, but the present invention is not limited to this, and functional inks such as fluorescent inks, phosphorescent inks, and livestock inks can be used. , Photochromic ink, thermochromic ink, electric luminescent ink, infrared transmitting / absorbing ink, metallic ink, color shift ink, pearl ink, metallic luster ink, magnetic ink, conductive ink, insulating ink, biocode ink, Radiation ink, water and oil repellent ink, foam ink, fragrance ink, ink eraser It may be used and the reaction ink or the like.

Further, in the third embodiment, ultraviolet rays are used as a light source for light emission, and in such a case, the opportunity to be irradiated with ultraviolet rays is very rare in normal use, and therefore, in normal use.
